Definitions

  • the invention relates to a heating medium distributor for a supply system comprising several heat exchangers according to the preamble of patent claim 1.
  • supply air systems in which a plurality of heat exchangers are arranged in parallel for heating the air to be conditioned.
  • a heating medium distributor supplies heated heating medium, in most cases hot water, to the individual heat exchangers and discharges the heating medium cooled after passing through the heat exchanger.
  • Known heating medium distributors are produced by soldering or welding individual pipe pieces together. This is associated with laborious manual work, which requires qualified personnel.
  • these known heating medium distributor build comparatively large, since all welds must be accessible. As a result of this large design, the heating medium distributors normally do not have to be installed in the housing of the supply air system but must be attached to this or to this. For this reason, they must be provided with a complex heat insulation.
  • a heating medium distributor of the type mentioned is from the CH 533 382 known.
  • Whose housing is composed of two trough-shaped housing halves, separated by a partition form a flow and a return collection chamber and each have welded pipe sections as connection channels for heat exchangers.
  • a housing for a heating medium distributor similar to that of the aforementioned type shows the DE 41 05 812 A1 ,
  • This housing essentially comprises three housing parts, which each consist of multiple angled sheets. By bending a certain inherent rigidity of the semi-finished products is achieved. Such cases also show the DE 200 10 701 U1 as well as the DE 297 02 573 U1 ,
  • a housing with a circular cross-section shows the EP 0 818 659 A2 , in which transverse to the longitudinal extent of the tube in a plane feed and return lines open.
  • the housing is traversed along its axis by a sinuskurven similar corrugated partition, which separates the flow chamber from the return chamber.
  • Object of the present invention is to provide a heating medium distributor of the type mentioned, which is cheaper to manufacture and requires little space.
  • the heating medium distributor itself is no longer composed of pipe sections, but essentially formed by a box-like housing, which - far away from the supply air system to which it is to be mounted - are manufactured with largely automated processes can. In this way the quality of joints is increased at a lower cost.
  • the box-like housing can be housed in a larger or smaller flow paths in a smaller space than the aforementioned heating medium distributor. With larger flow cross sections, the flow velocity and the flow resistance decrease, which leads to more favorable operating costs.
  • Such a heating medium distributor can factory complained in the housing of the supply air system, tested there and then transported together with the supply air system to the end customer, whereby the installation time is reduced at the end customer.
  • the housing is divided by two partitions into three flow chambers, the first of which serves as a supply manifold and the second and third communicate with each other in an end region and together serve as a return manifold, ie the heating medium returning from the heat exchangers first passes through the distributor in one direction , then makes a turn by 180 ° and flows back in opposite directions.
  • the connections, via which the heating medium distributor, the hot heating medium supplied and from which the cooled heating medium is discharged can be provided in the same end region of the housing.
  • the housing is composed of commercially available semi-finished product. As such semi-finished flat plates or sheets, curved sheets or the like. In question, the best still be tailored and then connected to each other. This also significantly reduces the costs associated with the manufacture of the heating medium manifold of the present invention.
  • the housing may in particular be welded together from steel parts be.
  • all the supply connection supports and all return connection pieces are arranged on the same approximately parallel to the partition side of the housing, wherein the flow connection piece or the return connection pieces pass through the adjacent side of the housing flow chamber.
  • This heating medium distributor can thus be arranged for example above the various heat exchangers in the housing of the supply air system and connect directly to the terminals of the individual heat exchanger via its connection piece.
  • the flow connection piece and the return connection piece are arranged on a side of the housing extending approximately perpendicular to the partition wall, are laterally offset slightly from one another and thus open directly into the corresponding flow chambers.
  • penetrations of connecting pieces through a flow chamber can be dispensed with, which may however necessitate a somewhat more complicated line routing outside the distributor.
  • the heating medium distributor As already mentioned above, it is possible due to the small size of the heating medium distributor according to the invention in many cases, to accommodate the heating medium distributor within the housing of the supply air system. In this case, the housing of the heating medium distributor itself requires no thermal insulation, which again brings a significant cost advantage.
  • heating medium distributor is used to supply heating medium, for example, hot water, a plurality of heat exchangers.
  • heating medium for example, hot water
  • heat exchangers not shown in the drawing are located in a supply air system, as found for example in paint shops and there conditioned the supply air for the spray booth, in particular heated.
  • the heating medium distributor 1 has a box-shaped housing 2, which is made essentially of commercially available sheet metal semi-finished products.
  • This housing 2 comprises a rectangular, flat top 2a, a correspondingly shaped rectangular, planar bottom 2b, two semicircular curved in cross-section side walls 2c and 2d and two correspondingly shaped end walls 2e and 2f, which can be understood as rectangles with attached to the narrow sides semicircular surface portions.
  • the housing 2 is divided into two flow chambers 5, 6, 7 by means of two partitions 3, 4, which extend perpendicularly to the upper and lower sides 2b of the housing and are tightly connected thereto.
  • the first partition wall 3 starts at the in FIG. 2 left end wall 2e, on a line through which the long dimension of the end wall 2e is divided in the ratio 1: 2.
  • This first partition 3 extends over a relatively short distance parallel to the side walls 2c and 2d of the housing 2 and is then through a wall piece 3a, which is parallel to the end wall 2e, about one third of the width of the housing 2, seen in the direction of the longitudinal extent the end wall 2e, offset in parallel.
  • a further partition wall section 3c is thus attached to the partition wall section 3b, which now again runs parallel to the side walls 2c and 2d again and up to the in FIG. 2 led right wall 2f of the housing 2 and is welded there with this.
  • a first flow chamber 5 is formed in this way. This is somewhat widened in the region 5a adjacent to the left end wall 2e in relation to the remaining region 5b.
  • the second partition wall 4 is at a certain distance from the partition wall portion 3b parallel to this attached to the partition wall 3 with a portion 4a, which in turn is about one third of the longitudinal dimension of the end walls 2e and 2f in the direction of in FIG. 2 upper side wall 2c extends.
  • this section 4a is then a parallel to the side walls 2c and 2d extending partition wall section 4b, which at a certain distance from the in FIG. 2 right side wall 2f ends.
  • the between the first partition 3 and the in FIG. 2 The upper side wall 2c lying interior of the housing 2 is thus divided by the second partition 4 into two flow chambers 6, 7, which in the FIG. 2 right end of the housing 2 communicate with each other.
  • the in FIG. 2 The upper side wall 2c adjacent third flow chamber 7 is widened in a lying between the portion 3b of the first partition wall 3 and the portion 4a of the second partition wall 4b region 7a.
  • the widened region 5a of the first flow chamber 5 opens from above, so the housing top 2a by passing, approximately in the middle of the transverse dimension of the housing top 2a a Zuflußstutzen 8 through which the hot heating medium in the first flow chamber 5 of the manifold 1 can be introduced.
  • the widened region 7a of the third flow chamber 7 opens in a similar manner from above, the housing top 2a piercing, a return connection 9, through which the medium which has flowed through the manifold 1 and the heat exchanger, can be discharged.
  • each of these connecting pieces 10, 11 includes outside the housing 2 serving as a connecting piece of flexible hose 10a and 11a and a connecting flange 10b and 11b.
  • All parts of the distributor 1 are preferably made of steel and are tightly welded at the points where they are connected to each other.
  • the distributor 1 described above can be mounted within the housing of the supply air system in the immediate vicinity of the heat exchanger.
  • This has the advantage that the distributor 1 unlike the hitherto known, composed of individual pieces of pipe distributor, which had to be arranged outside the housing of the air supply system, does not need to be isolated.
  • the distributor 1 of the Zuflußstutzen 8 with the house-side flow line of the heating medium
  • the return pipe 9 with the house-side return line of the heating medium
  • the flow connection piece 10 with the corresponding flow connections of the heat exchanger and finally the return connection piece 11 mitden the return connections of the individual heat exchanger connected. Due to the flexible hose pieces 10a, 11a while certain dimensional variations in the position of the connections of the heat exchangers can be compensated, so far as no high welding accuracy can be maintained got to.
  • hot heating medium flows into the first flow chamber 5 via the inlet connection 8 on the upper side 2 a of the distributor 1. It is from there via the flow connection piece 10 in the in FIG. 2 led lower side surface 2d to the various heat exchangers, where it gives off its heat partly to the air to be heated. From each heat exchanger, the cooled heating medium returns via a return connection port 11a in the manifold 1, flows through there first, the first flow chamber 6, then bends at in FIG. 2 right end of the housing 2 by 180 °, in opposite directions flows through the third flow chamber 7 and is finally discharged via the return connection 9 at the top 2a of the housing 2 to the house-side return line.
  • the arrangement of the supply and return connection pieces 10 and 11, via which the individual heat exchangers are supplied corresponds to the Tichelmann principle. This means that the path of the heating medium through the manifold 1 and the heat exchanger for each heat exchanger is the same length, so that all heat exchangers are supplied in the same way with heating medium.
  • the described distributor 1 may be designed in a modular manner. This means that it consists of identical sections at least in its central region, in each of which the three described flow chambers 5, 6, 7 are formed and which have a certain number of connecting pieces 10, 11 for heat exchangers.
  • the widened areas 5a, 7a of the flow chambers 5, 7, the inflow pipe 8 and the return connection 9 in the housing top 2a and the connection between the flow chambers 6 and 7 are in these middle sections th of the distributor 1 but not available.
  • Return pipe 11 may optionally be waived if care is taken in the precision of the welds both the manifold 1 and during assembly of the heat exchanger on high precision. Such rigid connecting pieces 10, 11 are of course cheaper.
